How to read this profile

The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.

We track GPT Realtime 2.1 Mini, but no weighted text-model benchmark result is published on the site yet. This page shows the metadata and separate protocol evidence we can verify now; a BenchLM score will appear only if compatible public evaluations land.

GPT Realtime 2.1 Mini is a proprietary model with a 128K context window. No explicit reasoning mode is documented in this profile.

Available on the OpenAI Realtime API as gpt-realtime-2.1-mini since July 6, 2026, with text, audio, and image input, text and audio output, a 128,000-token context, 32,000-token maximum output, function calling, and prompt caching.

GPT Realtime 2.1 Mini is a display-only distilled speech-to-speech reasoning model for lower-cost voice agents on the Realtime API. Voice-protocol results remain separate from BenchLM’s weighted text-model ranking.

The profile has no source-displayable benchmark row yet.

Frequently asked questions

How does GPT Realtime 2.1 Mini perform overall in AI benchmarks?

GPT Realtime 2.1 Mini does not have any source-displayable benchmark rows yet, so this profile does not assign a public score or rank. Documented specifications remain visible, while score-led charts and claims stay unavailable until a published evaluation can be attached to the exact model.

Does GPT Realtime 2.1 Mini have full benchmark coverage on BenchLM?

No. GPT Realtime 2.1 Mini currently has 0 source-displayable rows across 434 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.

What is the context window size of GPT Realtime 2.1 Mini?

GPT Realtime 2.1 Mini has a documented context window of 128K. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
